Title was: ICE(expression.c) accessing out of bounds element in a static array
constant initialized through struct literal
Changed since it is more general. Applies to D2 as well as D1.
-- ANALYSIS --
This is crashing in constfold.c, line 1218, crashing while doing e1-toChars()
while printing the error message. But there are also rejects-valid bugs with
the
same root cause: block assignment of arrays is buggy.
The root cause is expression.c, StructLiteralExp::getField().
In the line e-type=type is incorrect if e-type is of type K, and 'type'
is a static array of type K.
PATCH: in such cases, create and populate an array literal.

struct S { int i[3]; }
enum S s = S(8);
